Abstract

The invention provides a turbofan which can stably support a blade part and can easily perform welding operation. The turbofan comprises a mainboard (24), a cover (26) and a plurality of blade parts (27), wherein blade parts (27) comprise flange portions (45), the flange portions (45) are welded to the mainboard (24), so that the blade parts (27) are jointed to the mainboard (24).

Description

technical field [0001] The present invention relates to a turbo fan, and more particularly, to a turbo fan capable of stably supporting a blade member and enabling easy welding. Background technique [0002] Conventionally, there is known a turbofan mounted in an indoor unit of an air conditioner, etc., and composed of a main board, a shroud, and a plurality of wings (sheets). [0003] As such a turbofan, the prior art discloses a technique in which, for example, a main plate having a hub fixed to a rotating shaft of a motor at the center, a cover forming a suction guide wall, and a plurality of blade members are individually molded using thermoplastic resins. , the main board has a fitting portion fitted with a plurality of blade parts, and the cover has a fitting portion fitted with a plurality of blade parts, and the plurality of blade parts are fitted with a plurality of parts of the main board and the cover in a manner parallel to the rotation axis. The parts are fitte...
